Fig. 4

Example of venous scoring during high preload condition. A The hepatic vein Doppler at the bottom with labeled a, s and d waves showing an S > D morphology. B The portal vein showing the maximum and minimum velocities use to calculate the portal pulsatility index. C The renal artery and vein revealing a ‘pulsatile fused’ or ‘short end-diastolic pause’ morphology. D The carotid artery and jugular venous spectra from the wearable Doppler. The jugular has an S > D morphology most comparable to the hepatic vein
